TECHNICAL FIELD

The present application relates to the field of fitness equipment, further to the field of rowing machines, and specifically to a folding rowing machine that is simple and fast to unfold or store.

BACKGROUND

As we all know, the rowing machine in fitness equipment generally mainly includes a main frame and a slide rail, while pedals and handles are arranged on the main frame, and a cushion is arranged on the slide rail. When exercising, a user can press against the pedals with feet, hold the handles with hands, sit on the cushion, and then pedal forcibly with legs to make the cushion reciprocate on the slide rail. Thereby both leg strength and psoas muscles can be exercised.

Due to the long shape of the rowing machine, in order to facilitate storage, the main frame and the slide rail of the rowing machine are often connected by hinges, so that the slide rail and the main frame can be folded when being stored, thereby significantly saving the space occupied by the rowing machine. However, it is troublesome to unfold or fold and store the existing rowing machine by a hinge structure. For example, in a slide seat device of a rowing machine disclosed in Chinese utility model patent with application number 203447711, the positioning and fixing of a hinged structure is realized by a threaded engagement of a slide rail locking knob and rotation fixing seat. When the unfolding or folding operation is required, the slide rail locking knob needs to be unscrewed first and then the slide rail is unfolded or folded, which is troublesome. Especially when switching from a folded and stored state to a used unfolded state, because the slide rail is only fixed by the slide rail locking knob, when the slide rail locking knob is unscrewed, the slide rail has no another fixing structure, and is simple to drop down on its own and hurt others. Generally, one hand holds the slide rail, and the other hand operates the slide rail locking knob; alternatively, one person operates the slide rail locking knob and another person holds the slide rail; the operation is more difficult.

Further, the main frame is provided with a lifting handle.

The technical solutions provided by the present application have the following beneficial effects:

When the rowing machine is in an unfolded usage state, a limit rod of a fixing assembly is clamped on a usage stop groove, thereby fixing a slide rail frame. When the slide rail frame needs to be folded, a user steps on a pedal member with feet and steps down to disengage the limit rod from the usage stop groove, thereby folding the slide rail frame. After the slide rail frame is folded to a corresponding state, the pedal member loses the pedaling force, and under the action of an elastic member, the limit rod is clamped and fixed on a storage stop groove to fix the slide rail frame in a stored state. Similarly, when the rowing machine needs to be unfolded, the user holds the slide rail frame with hands, steps on the pedal member with feet and steps down to disengage the limit rod from the storage stop groove, thereby putting down the slide rail frame safely. The above operations are all completed by a single person, and are simple and fast.

The assemblies in the drawings are not drawn to scale, and similar assembly symbols are usually used to indicate similar assemblies.

The present application will now be further described with reference to the drawings and specific embodiments.

Referring to FIGS. 1 to 8, a folding rowing machine provided by the present embodiment includes a main frame 10 fitted with a damping mechanism 11 and a slide rail frame 20 provided with a cushion 21. The damping mechanism 11 has a handle 12 to pull the damping mechanism 11. A pedal plate 13 for pedaling during exercise is further arranged on the main frame 10 to facilitate the fitness exercise of the rowing action. The arrangements of components of the rowing machine belong to the prior art and will not be described in detail here.

The main frame 10 and the slide rail frame 20 are hinged, the folding rowing machine further includes a fixing assembly 30, the fixing assembly 30 includes a swing rod 31 hinged on the main frame 10, a limit rod 32 connected to the swing rod 31, and an elastic member 34 and a pedal member 33 connected to the limit rod 32, an arc-shaped abutting surface 401 which swings synchronously with the slide rail frame 20 is arranged at a position where the slide rail frame 20 and the main frame 10 are hinged, a usage stop groove 402 and a storage stop groove 403 are recessed and formed on the arc-shaped abutting surface 401, the elastic member 34 applies, to the limit rod 32, an elastic force for making the limit rod 32 abut against the arc-shaped abutting surface 401, when the slide rail frame 20 swings relative to the main frame 10 to an unfolded state or a folded state, the usage stop groove 402 or the storage stop groove 403 on the arc-shaped abutting surface 401 is clamped and fixed with the limit rod 32 of the fixing assembly 30; that is, as shown in FIGS. 5 and 6, in the unfolded state, the usage stop groove 402 is clamped and fixed with the limit rod 32; as shown in FIGS. 7 and 8, in the folded state, the storage stop groove 403 is clamped and fixed with the limit rod 32. The pedal member 33 extends to outside of the main frame 10, and pedaling on the pedal member 33 drives the limit rod 32 to overcome acting force of the elastic member 34 and swing toward a direction away from the arc-shaped abutting surface 401.

When the rowing machine is in an unfolded usage state, the limit rod 21 of the fixing assembly 30 is clamped on the usage stop groove 402, thereby fixing the slide rail frame 20. When the slide rail frame 20 needs to be folded, a user steps on the pedal member 33 with feet and steps down to disengage the limit rod 32 from the usage stop groove 402, thereby folding the slide rail frame 20. After the slide rail frame 20 is folded to a corresponding state, the pedal member 33 loses the pedaling force, and under the action of the elastic member 34, the limit rod 32 is clamped and fixed on the storage stop groove 403 to fix the slide rail frame 20 in a stored state. Similarly, when the rowing machine needs to be unfolded, the user holds the slide rail frame 20 with hands, steps on the pedal member 33 with feet and steps down to disengage the limit rod 32 from the storage stop groove 403, thereby putting down the slide rail frame 20 safely. The above operations are all completed by a single person, and are simple and fast.

The first hinged shaft 35 is arranged to facilitate hinged arrangement between the swing rod 31 and the main frame 10. Of course, in other embodiments, the first hinged shaft 35 may not be arranged, and a hinged hole may be defined directly in an end portion of the swing rod 31 for hinge connection.

Preferably, in this embodiment, the elastic member 34 is a tension spring, and the tension spring applies, to the limit rod 32, a tensile force for making the limit rod 32 abut against the arc-shaped abutting surface 401.

Specifically, the swing rod 31 is provided with a connecting ring, one end of the tension spring is hooked on the main frame 10, and the other end is hooked on the connecting ring of the swing rod 31, thereby completing the assembly of the tension spring, that is, the indirect connection of the limit rod 32, and the structure assembly is simple.

Of course, in other embodiments, the assembly structure of the tension spring may also adopt other methods, for example, the tension spring is directly connected to the limit rod 32. Alternatively, other types of elastic members, such as torsion springs, can be used, as long as this elastic member can apply, to the limit rod 32, an elastic force for making the limit rod 32 abut against the arc-shaped abutting surface 401.

Preferably, in this embodiment, the pedal member 33 and the swing rod 31 are an integral connection structure, and the pedal member 33 is a pedal plane formed by integrally bending a rod member. The pedal member 33 and the swing rod 31 can be directly and integrally formed by one rod, and the connection operation is simple. Of course, in other embodiments, the pedal plate 33 and the swing rod 31 may also be different devices, and are connected to the limit rod 32 respectively.

Preferably, in this embodiment, a hinged member 40 is detachably fixed on the slide rail frame 20, and the slide rail frame 20 is hinged to the main frame 10 through the hinged member 40 to facilitate replacement of parts, that is, when the hinged member 40 is damaged, it is detached and replaced without replacing the entire slide rail frame 20; in terms of preparation, the slide rail frame 20 and the hinged member 40 have different shapes and can be prepared separately, which is convenient for operation. Of course, in other embodiments, it is not limited to this.

Specifically, the hinged member 40 includes a second hinged shaft 41 and a fan-shaped connecting piece 42 connected to the second hinged shaft 41. The hinged member 40 is hinged to the main frame 10 through the second hinged shaft 41 to realize hinged arrangement between the main frame 10 and the slide rail frame 20. An arc-shaped section of the fan-shaped connecting piece 42 is the arc-shaped abutting surface 401, and the usage stop groove 402 and the storage stop groove 403 are defined on the arc-shaped section of the fan-shaped connecting piece 42.

More specifically, there are two fan-shaped connecting pieces 42, the two fan-shaped connecting pieces 42 are arranged at an interval, the swing rod 31 is connected to a middle position of the limit rod 32, the first hinged shaft 35, the swing rod 31 and the limit rods 32 together form an I-shaped structure, the swing rod 31 is located in a gap between the two fan-shaped connecting pieces 42, and two ends of the limit rod 32 form abutting engagement with the arc-shaped sections of the two fan-shaped connecting pieces 42 respectively. With this structure arrangement, the force engagement of the limit rod 32 and the arc-shaped abutting surface 401 is more uniform and is not simple to dislocate, and the connection stability is better.

Of course, it is not limited to this in other embodiments.

Preferably, in this embodiment, the main frame 10 is provided with a lifting handle 14, and the purpose of arranging the lifting handle 14 is in that: when the slide rail frame 20 is put down to the unfolded usage state, if the slide rail frame 20 is not unfolded in place, the lifting handle 14 can be pulled up so that the limit rod 32 can be fully clamped into the usage stop groove 402.

Preferably, as shown in FIG. 7, in this embodiment, the bottom of the slide rail frame 20 is further provided with a foldable pulling handle 22 and a clamping member 23 for fixing the folded pulling handle 22. When the rowing machine is folded to the folded and stored state as shown in FIG. 7, the pulling handle 22 can be unfolded, and the rowing machine can be pulled by the pulling handle 22 to move. When there is no need to move, the pulling handle 22 can be folded and clamped to the clamping member 23 for fixing.
